Abstract
The utility model discloses a branched silencer. The branched silencer comprises a main gas inlet pipeline, a branched silencing pipe and a piston, wherein the branched silencing pipe is communicated with the main gas inlet pipeline; and the piston is arranged in the branched silencing pipe and can move along the inner wall of the branched silencing pipe. The branched silencing pipe also comprises a frequency scale which is parallel to the branched silencing pipe and is carved with frequency values and height values corresponding to the frequency values. The piston is in threaded matching with the inner wall of the branched silencing pipe. The branched silencing pipe is welded to the main gas inlet pipeline, and the branched silencing pipe and the piston form a quarter-wavelength pipe. The branched silencer disclosed by the utility model has the advantages that the silencing frequency can be adjusted, the structure is simple, the reading is reliable, and the application flexibility is very strong.
Description
Technical field
The utility model relates to the auto parts and components field, more particularly, relates to a kind of collateral branch silencing apparatus.
Background technique
The main structure of collateral branch's silencing apparatus of available technology adopting is following: collateral branch's hush tube of an endcapped of welding on the air inlet main pipe, collateral branch's hush tube is communicated with the air inlet main pipe, constitutes the quarter-wave long tube jointly, realizes the purpose of eliminating the noise.
Collateral branch's hush tube of endcapped can only carry out the noise elimination of single-frequency, and operating flexibility is relatively poor, when the inconsistent situation of face of noise frequency spectrum, can't play effective noise elimination effect.
The model utility content
The utility model is intended to propose a kind of collateral branch's silencing apparatus that can regulate frequency of noise elimination.
According to an embodiment of the utility model, a kind of collateral branch silencing apparatus is proposed, comprising:
The air inlet main pipe;
Collateral branch's hush tube is communicated with the air inlet main pipe;
Piston, being arranged on also can be along the interior move of collateral branch's hush tube in collateral branch's hush tube.
In one embodiment, collateral branch's silencing apparatus also comprises the frequency scale chi, and the frequency scale chi is parallel to collateral branch's hush tube setting, is carved with frequency values and corresponding height value on the frequency scale chi.
In one embodiment, the inwall of piston and collateral branch's hush tube passes through screw-thread fit.
In one embodiment, collateral branch's hush tube is welded to the air inlet main pipe, and collateral branch's hush tube and piston constitute the quarter-wave long tube.
Collateral branch's silencing apparatus of the utility model can be regulated frequency of noise elimination, and simple in structure, reliable reading, has very strong application flexibility.
Description of drawings
The utility model above-mentioned and that other characteristic, character and advantage will become through the description below in conjunction with accompanying drawing and embodiment will be more obvious, identical in the accompanying drawings reference character is represented identical characteristic all the time, wherein:
Fig. 1 has disclosed the structural drawing according to collateral branch's silencing apparatus of an embodiment of the utility model.
Embodiment
With reference to shown in Figure 1, the utility model has disclosed a kind of collateral branch silencing apparatus 100, comprising: air inlet main pipe 102, collateral branch's hush tube 104, piston 106 and frequency scale chi 108.
Collateral branch's hush tube 104 is communicated with 102 with the air inlet main pipe.In one embodiment, collateral branch's hush tube 104 is welded to air inlet main pipe 102.
Piston 106 is arranged on also can be along the interior move of collateral branch's hush tube 104 in collateral branch's hush tube 104.In one embodiment, piston 106 passes through screw-thread fit with the inwall of collateral branch's hush tube 104.Collateral branch's hush tube 104 together constitutes the quarter-wave long tube with piston 106.
Collateral branch's silencing apparatus 100 of the utility model welds together collateral branch's hush tube and air inlet main pipe and interconnects, and in collateral branch's hush tube piston is set, and the inwall of piston and collateral branch's hush tube joins through screw thread.Like this, collateral branch's hush tube and piston have constituted the quarter-wave long tube jointly.Piston during regulating frequency in the rotation collateral branch hush tube with the position of adjustment piston in collateral branch's hush tube, and then reaches the purpose of adjusting frequency of noise elimination.Through measuring the length of piston, can contrast the frequency of noise elimination that the frequency scale chi is read the quarter-wave long tube to collateral branch's hush tube root.
Collateral branch's silencing apparatus of the utility model can be regulated frequency of noise elimination, and simple in structure, reliable reading, has very strong application flexibility.
The foregoing description provides to being familiar with personnel in related domain and realizes or use the utility model; Being familiar with those skilled in the art can make various modifications or variation to the foregoing description and not break away from the model utility thought of the utility model; Thereby the protection domain of the utility model do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
